I have been in a mental hospital 10 years, and I am finally graduating.

I think how awesome I was. I played games all night without eating or sleeping for three days. I am a famous celebrity on campus. However, my parents think this is not a good thing. After repeated unsuccessful persuasion, they conspired against me and sent me to a mental hospital while I was not paying attention.

This mental hospital exudes an unusual smell. The patients inside are quiet and their eyes are full of wisdom. Soon, I understood the reason.

When I first arrived here, I was locked in a small room with several thick books on advanced mathematics and mathematical analysis, as well as exercise books. The condition for leaving the small room is simple: I got full marks in the exam.

These textbooks are outrageous. It took me almost 1 year to get full marks.

After leaving the small room, I thought I could finally leave, but this was the real beginning.

The dean jumped out and smiled: I didn't expect it. There are also complex variable functions and functional analysis. Let's swim in the ocean of mathematics.

. . . . . .

So it took me ten years to graduate, and my eyes were full of wisdom.

I'm so touched to finally leave.
